IMPROVEMENT IN BRAKES FOR RAILWAY CARS.

Specification forming part of Letters Patent No. 124,985, dated March26, 1872.

Speciication describinganew and Improved Brake and Safety-Guard forRailroad Cars, invented by ANTON TATZEL, Sr., and FRIED- RICH KINN, ofNew York city, and the county and State of New York.

Figure l represents a vertical longitudinal section of a railroad carprovided with our improved brake and safety-guard. Fig. 2 is an invertedplan View of the same. Fig. 3 is a vertical transverse section of thesame on the line C O, Fig. l. Fig. 4 is a detail side view of a wheeland guard.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described and then clearly pointed outin thecla-im.

A in the drawing represents the frame of a car or carV truck ofsuit-able kind and size. B B are the wheels, mounted on axles C C thathave their bearings in suitable axle-boxes a a. D D are frames, pivotedto or hung upon the axles O C, and connected by arms b b rigidly withthe brake-shoes and guards E E. The frame cannot swing on the axle todrop the brake on the track, as rods G G, above the axle, connect itwith levers H H at both ends of the car, which levers H are locked insuitable manner. In case of an emergency, when the car approaches aplace of danger or a person falls in front of thewheels, the front leverH is quickly dropped by the attendant, which allows the rod G to bemoved forward andthe brake in front of the wheel, by its own weight andthe friction of the wheel, to drop upon the track right in front of thewheel, as indicated in Fig. 4. The wheel in its further motion runs uponthe concave part of the brake, and is thereby lifted from the track,spending its power against the shoe, while the motion of the ca-r isspeedily but gently arrested by the excessive friction of the brake-shoeony the track. The shoe E is anged, as at e, to prevent it from runningoil' the track. The rods F and G should be jointed, as in Fig.` 2, topermit lateral bending', which is necessary when the ear runs on acurve.

By the introduction of this invention we be lieve that many accidentswill be prevented to the cars in motion and to persons falling upon thetrack. The principle of increasing the friction upon the track insteadof the wheels, as hitherto, and of', at the same time, clearing thewheels from the track, introduces an entirely novel feature intorailroad engineering.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent` The brake mechanism, consisting of jointedrodsF G and levers H, combined and .arranged with brake-shoe framespivoted on the axles, as and for the purpose described.
